I have been working on a new admixture calculator whenever I have found some time from real life pursuits. However, that's still not ready and I have a lot of submissions. So I am posting the HarappaWorld results for them.

Do note that the admixture components do not necessarily represent real ancestral populations. Also, the names I have chosen for the components should be thought of as mnemonics to ease discussion. I chose them based on which populations in my data these components peaked in. They do not tell anything directly about ancestral populations. The best way to look at these admixture results is by comparing individuals and populations. Finally, the standard error estimates on these results can be about 1%. Therefore, it is entirely possible that your 1% exotic admixture result is just noise.

I got the first submissions of 23andme v4 data. There's about a 12-13% missing SNP rate of v4 with HarappaWorld. So I don't expect major noise problems, though noise will be higher than for 23andme v3 data.

FDA had asked 23andme to stop its direct-to-consumer genetic testing and as a result 23andme has issued the following statement:

After discussion with officials from the Food and Drug Administration today, 23andMe will comply with the FDA's directive and stop offering new consumers access to health-related genetic tests while the company moves forward with the agency's regulatory review processes.

Customers who purchased kits on or after the FDA's warning letter of November 22nd will not have access to health-related results. Those customers will have access to ancestry-related genetic information and their raw data without 23andMe's interpretation of that data. They may receive health-related results in the future, depending on FDA marketing authorization.

Customers who purchased kits before November 22, 2013 will continue to have access to all the reports they've always had.

While I am disappointed at this turn of events, for our project it does not change much since 23andme will still provide raw data downloads as well as ancestry information.
